MC74HC374A  
Octal 3-State Non-Inverting  
D Flip-Flop  
High−Performance Silicon−Gate CMOS  
The MC74HC374A is identical in pinout to the LS374. The device  
inputs are compatible with standard CMOS outputs; with pullup  
resistors, they are compatible with LSTTL outputs.  
http://onsemi.com  
Data meeting the setup time is clocked to the outputs with the rising  
edge of the clock. The Output Enable input does not affect the states of  
the flip−flops, but when Output Enable is high, the outputs are forced  
to the high−impedance state; thus, data may be stored even when the  
outputs are not enabled.

The HC374A is identical in function to the HC574A which has the  
input pins on the opposite side of the package from the output. This  
device is similar in function to the HC534A which has inverting  
outputs.
